15 Claims. (01. 197-133) This invention pertains to pin type strip feeding devices for progressively advancing strips of material having therein successions of longitudinally spaced feed holes and more particularly to a roller wherein a pin wheel unit may be interchangeably positioned in any one of a plurality of different axial positions.

For illustrative purposes, but with no intent to unduly limit the scope or app ication of the construction as well as the means and mode of operation of pin type feeding devices whereby they may not only be economically manufactured invention, it is herein illustrated and described 1 10 as applied to a platen roller for a writing or imprinting apparatus, tabulator or computing machine, or to a feed roll for an autographic register or analogous mechanisms wherein one or more strips-of record material are to be progressively advanced past a legend receiving position and prescribed areas thereof periodically registered with each other and with the recording position.

but will be universally adaptable to feeding punched material of different width or for advancing material in different transverse paths of travel,v capable of being easily and quickly in-. terchangeably connected in different operative positions, having relatively few parts and unlikely to get out of repair. y,

A further object of the invention is to provide a sectional feed or platen roll, the separable sections of which may be assembled in various sequence and combinations to afford different 5 spacing of multiple pin wheels or diiferentloca- It is to be understood, however, that the present device is'not limited to such use but may be embodied in other apparatus for diflerent purpose and for operation upon other than mani folding material. For example, in lieu of the pin wheel unit herein illustrated, the interchangeable member may comprise a gear wheel, a type wheel, or the like.

In writing and imprinting machines, autographic registers and analogous mechanisms, it is frequently desirable to vary the position of the strip feeding unit to accommodate record material of different width or for presenting the material in different legend receiving relation .to the writing or imprinting elements, or to agree with feed holes disposed in different transverse positions in the record strips to be fed.

To enable universal adaptability of the pin type feed roll herein illustrated, such roller is shown as comprising multiple sections of different lengths which may be assembled in different combinations and between any two of which the interchangeable pin wheel unit may be removably inserted. To facilitate insertion and removal of,

ber may be employed simultaneously, each unit is provided with a detachable sector, the removal of which enables the pin wheel to be engaged and disengaged laterally at will between any tions of a single pin wheel axially of the assembly in interposed position between the separable sections thereof.

A further object of the invention is to provid a pin wheel unit or analogous element whichis laterally engageable and disengag'eable with and from a mounting shaft.

A further object of the invention is to provide an assembly of roll sections and pin wheel units capable of interchangeable assembly in various combinations to readily and easily accommodate the device to various conditions of -use.

A further object of the invention is to providea removable pin wheel or analogous element and a mounting therefor with which the element is detachably engageable without the necessity of removing the mount.

A further object of the invention is to provide a pin wheel or analogous element and a mounting therefor with which, the pin wheel is laterally engageable and disengageable.

A further object of" the invention is to, provide a pin wheeler analogous element having therein a removable sector for enabling lateral engagement-and disengagement with a mounting shaft.

A further object of the invention is to provide an adjustable mount for a pin wheel or the like the pin wheel unit, of which any desired num- 45 two roll sections of the assembly. The roll sec- 0 tions and pin wheel units are provided with interengaging configurations in their adjacent faces by which upon compressive adjustment the members are interlocked inadJusted positions.

with which the pin wheel is laterally engageable.

A further object of the invention is to proone of several operative. positions and which embodies the herein mentioned advantageous structural features and meritorius characteristics.

' The object of the invention is to improve the 88 With the above primary and other incidental wherein is shown the preferred but obviously not necessarily the only form of embodiment of-thev invention,

Fig. 1 is a longitudinal sectional view of an assembled pin type platen roll having therein two relatively spaced pin wheel units.

Fig. 2 is a fragmentary exterior view of one of the pin wheel units and adjacent roll sections.

Fig. 3 is a transverse sectional view on line 33 of Fig. 1.

Fig. 4 is a perspective view of one of the removable pin wheel units showing the detachable sector disengaged therefrom.

able sector H, which may have either parallel or divergent sides and which is of a width at least equal to the diameter of the shaft 2 on which the slots 16 left in the pin wheel or other interchangeable elements by removal-of the sector I3.

I The opposite faces of the pin wheel or other interchangeable unit are formed with concentric ribs or beads l1, portions of which continue across the removable sector 13, and which agree a in contour and diameterwith the grooves 9 in Fig. 9 is an end view of one of the roll sections.

In Fig. 1 there is shown a platen roll for use in a typewriter, imprinting or tabulating machine or the like comprising a plurality'of separable and interchangeable roll sections lll assembled in axial alignment upon a supporting shaft 2 mounted in a suitable frame or carriage, of which fragmentary portions 3-3 are shown.- There maybe any number of the roll sections I, which are preferably of assorted lengths, but of .the same diameter. They may be interchangeably assembled upon the shaft 2 in different sequence or combinations as may be found. necessary to properly locate or space the detachable pin wheel or other operative elements which are positionable between any two roll sections l.

Each of the roll sections i comprises a tubular core 4, which may be of metal, fiber, molded plastic, or any other suitable material. Tightly pressed or otherwise secured in each end of the core 4 is a head 5. The terminals of the tubular core I are preferably recessed or rabbeted as at 6 to receive the heads 5. Peripherally surrounding,

the tubular core 4 of each section is a surface covering 1 of rubber, composition, fiber, or other surfacing material suitable for the particular operation to be performed. The terminal faces of the roll section heads 5 are concued or recessed as indicated at 8 and in each recessed or concavev demountably engageable.

The pin'wheel units shown at H) each comprises a disc H, from the periphery of which.

projects radially disposed circumferentially spaced feeding pins I2, which are engageable in longitudinally spaced feed holes; in a strip of material to be advanced. Each pin wheel or other interchangeable unit is provided with a detachthe terminal faces of the roll sections l. The concentric projecting ribs I'I seat within the grooves or channels 9 in the heads of contiguous roll sections and are held in interlocking assembled relation therewith by axial adjustment of the roll sections I under compression.

The shaft 2 carries at its opposite ends abutment heads l9 and 20, one of which, I9, is fixedly pinned or otherwise secured to the shaft 2. The opposite head 20 is free for axial sliding adjustment upon the shaft under influence of a compression collar 2|. screw threaded upon a collar 22 fixedly engageable in the shaft in any position of longitudinal adjustment by a set screw 23. By retractive adjustment of the screw threaded collar 2| the axial pressure upon the roll sections I may be relieved and sufllcient clearance afforded to permit retraction of the adjustable pressure head 20 and. corresponding axial adjustment of the several roll sections I-| relative one to another. This enables the roll sections to be separated a sufficient distance to disengage the annular ribs ll of an interposed pin wheel or other interchangeable element from the circular grooves or channels 9 in the adjacent roll section heads. This relative adjustment also unlocks the removable sector; I3 of the interposedwheel unit. When the roll sections are in interengaging relation with theinterposed wheel unit the continuing rib segment l'la on the removable sector l3, which also seatswithin the grooves or channels 9 of the roll section heads, serves to lock the sector I3 against removal.

The axial pressure upon the sections l havin been relieved and the sections separated, the sector [3 may be radially withdrawn entirely from the slot I6 in the wheel unit ll, whereupon the wheel unit itself may be withdrawn from between the adjacent roll sections 1 in the opposite direction from the shaft 2. The bottom of the slot l6, which is contoured to agree with the periphery of the shaft 2, the remainder of which bearing is formed in th inner end of the sector 13, carries a key or spline 24 engageable in the 'keyway 25 of the shaft 2 in any of the several positions in which the wheel unit may be engaged.

Having been thus removed from the assembly, the roll sections I may be variously shifted one relative to another to separate the assembly between any two selectedsections for reception of the wheel unit ll therebetween. To reengage the wheel unit II in the newly selected position is is only necessary to slide the wheel I l-between the ends of the separated roll sections l by causing it to straddle the shaft 2 within the slot l6 until the key or spline 24 engages in the keyway 2! of the shaft and the concentric locking rib I1 is in registry with the groove or channel 9 of the adjacent roll section heads. The disengaged sector I3 is then returned slidinglywithin the slot it until its ribs i1 a agree with the ribs ll of the wheel H and also register with the groove or channel 9 of the roll section head. Thereupon, by pressing the roll section I to ether axially and locking them under compression by adjustment of the screw threaded compression collar 2|, the reengaged wheel ii and its detachable sector are again locked in the newly selected position. 4

While, as before mentioned, the invention is especially applicable to strip feeding apparatus,

- venient method of locking the wheel in position and locking the removable sector l3 in its assembled relation with the wheel I I, other means may be provided, as for example, a series of studs or projections 18 on the wheel element engageable incorresponding holes in the roll head, as in Fig. 6, or'the relation of such interengaging parts may be reversed, the ribor head I! being formed on the head of the roll section and the corresponding groove or channel 9 formed in the wheel element. Likewise, in lieu of a relatively narrow sector slidable in a corresponding recess in the wheel, the wheel may be variously' divided into segments of greater or less extent capable of assembly about the supporting shaft as shown in Figs. 8 and 9.

'From the above description it will be apparent that there is thus provided a device of the character described possessing the particular features of advantage before enumerated as desirable, but which obviously is susceptible of modification in its form, proportions, detail construction and arrangement of parts without departing from the principle involved or sacrificing, any of its advantages. Y

While in order to comply with the statute the invention has been described in language more or less specific as to structural features, it is to be understood thatthe invention is not limited to the specific features shown, but that the means and construction herein disclosed comprise the preferred form of several modes of putting the invention into effect, and the invention is therefore claimed in any of its formsor modifications within the legitimate and valid scope of the appended claims.
